Alterkation question. .....

Hi all....

Doing a complete resto-mod to my 68 Barracuda Notch-back and want to go to the Alterkation suspension system.

Do I have to have the engine out to install it? For some reason I thought I saw somewhere that it could be installed with the engine in the car....but that doesn't seem right. ..?!

I'm going to strip the ENTIRE car anyway when it goes to paint but I'm trying to figure out what order I want to do all these projects.

Thanks in advance! !!

Jeff
